为了对常规单囊体飞艇和混合式飞艇各自的性能特点有更清晰的认识，分别设计了某常规飞艇和混合式飞艇的总体方案，建立了两类飞艇的分析模型，并从气动特性、浮升特性、重量特性、续航特性方面对二者的综合性能进行了比较和分析。研究表明：在体积相同的情况下，虽然混合式飞艇在阻力特性方面不如单囊体飞艇，但由于混合式飞艇动升力较大，并可以借助动升力来平衡燃油的消耗，且有效载荷大、载油量大、可操纵性好，更有利于长航时飞行。研究结果可为我国开展长航时和大载重飞艇研制提供一定的设计参考。%To make the performances of conventional ellipsoidal airship and hybrid airship more clear, firstly, the overall design of a conventional airship and a hybrid airship are accomplished respectively, then the analytical models of the two kinds of airships are established, both comprehensive performances of aerodynamics, lift, weight, duration and maneuverability are compared and analyzed. It is found that drag of hybrid airship is not as good as conventional ellipsoidal airship in the case of same volume, but hybrid airship＇s dynamic lift is large, and can compensate the oil consumption. Furthermore, the characteristics of heavy payload, large oil-loaded, fine maneuverability of the hybrid airship are fit for the long endurance flight. The study results can be of certain references to the development of heavy-load airship.
